Giriraj Swami read and spoke from Srimad-Bhagavatam 2.3.23.
“In order to make our theoretical knowledge realized we should repeat the knowledge. It’s a very simple process, but when you repeat something you get realization of what you are saying. One of Srila Prabhupada’s early disciples had read that the moon was created by the churning of the ocean of milk—which seemed fantastic. She asked Srila Prabhupada, ‘What does that mean?’ Srila Prabhupada said, ‘Just repeat: “The moon was churned from the ocean of milk.”And she did. Again he told her, ‘Repeat.’ And again, ‘Repeat.’ So she repeated it several times. Then he asked, ‘Now do you understand?’ And she replied, ‘Yes. The moon was churned from the ocean of milk.’ So by repeating what we have learned—by repeating what we have heard—we get realization.”
